Hello Philip,

If there is a choice between solving a huge puzzle and going to college,
I highly suggest college! Taking the plunge and going back to school was
one of the most frightening things that I ever did, so I can understand.
It was also one of the best times for me, being exposed to so many
bright people and new ideas. Also, I bet you can work twisty puzzles
into your school projects so it’s not like you must choose one or the other.

Regarding physical implementations, I’m convinced that MC4D is indeed
possible but is waiting for someone to have that spark of inspiration.
Oskar van Deventer came up with the "Roadblock" cube which looks just
like a 2^4 and even supports a center-cut twist that is exactly like one
type of 4D twist: It’s not
quite 4D yet but I’m betting we’ll see a true physical 4D puzzle someday.

Then solving it took about a year! O.O I figure if I can solve a 3^5 hypercube without macros, then what’s 1 more dimension? :) It will probably take me a good 3 months, though. Maybe even more. It all depends if I am courageous enough to go to college or not this year…
> As for a twisty puzzle program that you can rotate by screen swiping; that sounds awesome!! :D It’s one step closer to a physical 4d cube! Boy I wish a mech was easy enough to construct! :/ Maybe it is, but we just haven’t stumbled upon a solution… Yet. :)

I’m really afraid that with the current parameters that it will be impossible to see what is really staying put and what is not. If only certain layers could be hidden like in Roice’s 120cell program. I think that for now it may be wisest to try to solve 3^6 first. That way I can focus all of my attention on this monster! Especially because it would be very easy to forget algs on this one… Well, wish me luck. This one will not be easy at all! O.o

I spent a whole week devoting to learning every possible rotation of the hypercube faces and I actually began solving it before I finished Mht633 52 colored! I originally downloaded this beast to my computer as a joke, not really expecting myself to comprehend it. However, a few months after I solved Mht633 and after I was starting to get over the pain of my divorce was actually when the real work began. I had to keep changing perspectives probably at least 1000 or more times, because I needed to get the pieces into a lesser dimensional perspective… One that I could actually understand. I did full 3 layer rotations a lot because the pieces that were within the same block were deceptively far apart in distance and single 3 cycles were not enough to permute them. So I had to change paradigms so I could see where they REALLY

>>>> I think that I will also be working on the 120cell halfcut during my 3^6 solve, but I don’t really think that I can solve it as of now. There are so many parts moving through space that I find it hard to find any algs that are useful. Maybe I can solve it. I sure will try my hardest!!! :) Maybe I’ll have it solved within a year or two! :P

I just went through a sad divorce with my wife of almost 4 years, so I’ve been too depressed to write anything; but I am now back with exciting news! I am now #5 in the world to solve Magic Cube 7d! :D Boy, this has DEFINATELY been the most complex twisty puzzle that I have ever solved! o.o However, you can only view the last 300,000 moves. For some strange reason the program stops one you get down to the 991,771st move! :/ Now I think that I will attempt to solve 3^6 cube WITHOUT macros, ‘gulp’, so everybody can actually view the log file without lag or bugs! Wish me luck!
